Uncle part 2

By age 7 me and my sister were staying at my grans house every school holidays my sister being 11 at this point. We had a double bed in a small bedroom which we shared and played dirty games practically every night touching each other’s pussy.
One afternoon my gran had gone out and my uncle was at work when we started looking through a pile of VHS videos that were in a cupboard. Putting one on we found a typical 80s porno. Hairy men big cocks, big haired women surrendering to the men begging for them to fuck their hairy pussies. I remember being amazed and sitting watching feeling a familiar tingle between my legs. My sister was on the sofa hands down her panties fingering herself before she pulled down her panties and asked me to finish her off with my tongue. The video was still on in the background as i ate her pussy on the living room floor. When we started watching again there was a lesbian scene on with one woman sat on the others face. By this time i needed some relief and asked if I could sit on my sisters face to see what it felt like. She agreed and as i took my panties off I remember seeing a huge wet spot on the crotch, that was the first time i think i got wet. I then sat on her face and started humping lasting about a minute before cumming. Thankfully we didn’t get caught that afternoon.

A few days after i was in the bedroom panties downing humping the bed when i heard someone behind me turning around i saw it was my uncle who had a big smile on his face which meant I wasn’t in trouble.he told me how my sister had told him what we had watched and asked if i wanted to play with him. I agreed and he took out his cock and told me to suck on it. I’d seen it on the video and i knew my sister did it for him so kind of knew what to do although I wasn’t great he got hard in my mouth and had me kneel on the floor while he finished himself off cumming on my face. He laughed and wiped it off with his hands saying i deserved a reward and should sit on his face like the video which i did but i was too nervous to enjoy it and couldn’t cum. He told me to lie back on the bed and started kissing me with a lot of tongue while he pushed his hand hard against my pussy this time i did cum quite hard and loud which he muffled with his tongue deep in my mouth.

It was a few months later probably the next school holidays when i saw his fucking my sister. We were both asleep in bed when he came into the room i woke up as he was lifting the covers on her side of the bed and pulling up her nightie. He didn’t see me watching at this point he took out his cock which was already hard and put his hand between my sister legs rubbing her pussy. We had been licking each other before we went to sleep so she was already wet. He bent down and i heard him whisper “someone has been thinking about my cock again” she laughed and swung her legs out of the bed so she was bent forward her arse in the air “good girl, ready for me” he whispered as he stroked his cock hard and pushed it into her and started to fuck her. I was getting turned on at this point and must have moved because he saw i was watching but wasn’t happy and angrily told me to push my face in the pillow and not move. He fucked her for just a few minutes before i heard a grunt. I then heard him walking around the bed and bend over me whispering in my ear “keep quite or it will be the big belt and i will tell your father everything”
